(a) Fluorescence signal collected from viruses in three channels, excited with both wavelengths λ = 520 nm and λ = 633 nm. They are labeled based on the number of peaks they have. (b) Zoomed in fluorescence signal of single virus detection for H1N1, showing three distinct numbers of peaks (10, 7 and 5), and coming from 3 separate channels.
